Description

Technical Field

[0001] This invention relates to the field of integrated ice-making devices, specifically to a tabletop integrated device for ultraviolet sterilization, water purification, heating, cooling, and ice making. Background Technology

[0002] The UV sterilization, water purification, heating, cooling, and ice-making integrated device is a comprehensive equipment that integrates water treatment, heating, cooling, and ice-making functions. It is commonly used in homes, offices, medical facilities, and other places, and has multiple uses, making it convenient for users to obtain purified water and manage temperature control.

[0003] Existing integrated ultraviolet sterilization, water purification, heating, cooling, and ice-making devices suffer from high power consumption and energy consumption due to their multiple functions. The ice-making function is usually the most energy-intensive. This is because traditional tabletop ice makers typically only have ice-making capabilities and lack freezing or cold-keeping functions. As a result, the ice produced will continuously melt. To ensure a constant supply of ice, the compressor needs to operate continuously. This continuous operation puts the compressor under high load for extended periods, leading to increased winding temperature, accelerated aging of insulation materials, carbonization of lubricating oil, decreased lubrication performance, and increased mechanical wear. The theoretical lifespan of the compressor may be shortened by 30%–50% (e.g., from 10 years to 5–7 years).

[0004] Furthermore, the ice produced by traditional integrated ice-making devices will accumulate in the ice storage tank. Since the ice storage tank does not have a freezing function, the ice in the ice storage tank may repeatedly melt and freeze when the ice is injected in batches, which may easily form large "ice lumps". This may cause the spiral ice extractor in the ice storage tank to be overloaded and the motor to stall and burn out.

[0005] Therefore, it is necessary to invent a tabletop ultraviolet sterilization, water purification, heating, cooling and ice-making integrated device. Summary of the Invention

[0011] Preferably, the propulsion ice-discharging mechanism includes a crossbeam, the middle of which passes between the U-shaped clamp and the slider. The U-shaped clamp has a groove on its inner side, and the crossbeam has a protrusion in its middle. The protrusion in the middle of the crossbeam is slidably installed in the groove on the inner side of the U-shaped clamp. Both ends of the crossbeam are slidably installed in sliding brackets.

[0012] Preferably, the cold water input pipeline includes a cold water inlet pump, the input end of which is connected to a cold water inlet pipe, the cold water inlet pipe is connected to a pure water tank, the output end of which is connected to a cold water input pipe, the cold water input pipe is connected to a cold water tank, and a cold water outlet pump is installed in the middle of the cold water output pipe.

[0013] Preferably, the two-stage heating pipeline includes a heating water inlet pump, the input end of which is connected to a heating water inlet pipe, the heating water inlet pipe is connected to a pure water tank, the output end of which is connected to the input end of a preheating pipe, the preheating pipe is disposed on the heat dissipation surface of the condenser, the output end of which is connected to the input end of an electric heater, and the output end of the electric heater is connected to the hot water input end of a mixing valve.

[0014] Preferably, a filter element bracket is installed inside the rear flip door, and both the PCT filter element and the RO filter element are inserted and installed in the filter element bracket. A first filter element interface and a second filter element interface are installed on the back of the heat insulation plate. The first filter element interface can be connected to the PCT filter element socket.

[0015] Preferably, the top surface of the ultraviolet disinfection base is provided with an ultraviolet lamp group, the front side of the ultraviolet disinfection base is also equipped with a water bottle, the lower end of the front panel is equipped with a water receiving tray, the middle of the front panel is provided with an ice outlet, the middle of the front panel is equipped with a water outlet, and the condenser heat dissipation surface is equipped with a cooling fan.

When ice is needed, the first evaporator is switched to perform forced heat exchange on the water in the cold water tank that is at the freezing point, so that it quickly crystallizes into ice. Then, the propulsion ice dispensing mechanism is activated to move the ice to the ice storage tank and then complete the ice dispensing, so as to effectively reduce the energy consumption of the compressor, make effective use of the cold energy generated by the condenser, and avoid the ineffective ice melting-re-ice making cycle inside the system.

[0018] This application also has the following advantages:

[0019] 1. Energy saving: For scenarios such as homes and offices where ice is used intermittently and in varying quantities, the energy-saving effect is most obvious, as there is no need to continuously consume electricity to maintain an "ice inventory".

[0020] 2. Ready to use immediately, fresh ice: The ice produced is for immediate use, has high hardness, melts slowly, and provides a good user experience.

[0021] 3. Higher integration: During the process of "room temperature water → 0°C storage water → rapid ice formation", it can share the refrigeration system and insulation cavity with the water dispenser's cold water system.

[0022] 4. Reduce peak power: Although the power is high when making ice quickly, the time is short. In contrast, when traditional ice makers start the ice-making cycle, the compressor also needs to run at high power to cool from high temperature, and the duration is longer.

[0038] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0039] like Figure 1 - Figure 6 As shown, a countertop ultraviolet sterilization, water purification, heating, cooling, and ice-making integrated device includes a casing 111, a central control system mounted on the top surface of the casing 111, a front panel 112 mounted on the front of the casing 111, a rear door 113 mounted on the back of the casing 111, a PCT filter 132 and an RO filter 133 installed inside the rear door 113, an ultraviolet disinfection base 114 mounted on the side of the casing 111, a pure water tank 116 mounted on the top surface of the ultraviolet disinfection base 114, a raw water tank 115 mounted on the top surface of the pure water tank 116, and a raw water tank 115 installed inside the casing 111. There is an insulation panel 141. An ice storage tank 151 and a cold water tank 154 are installed on the top surface of the insulation panel 141. A dual evaporation system is installed in the cold water tank 154. A compressor 142 and a condenser 143 are installed at the bottom of the outer casing 111. The output end of the compressor 142 is connected to the input end of the condenser 143 through a pipe. A mixing valve 185 is also installed on the inner wall of the outer casing 111. A cold water output pipe 194 is installed between the cold water input end of the mixing valve 185 and the cold water tank 154. A cold water input pipe is connected to the bottom of the cold water tank 154. A two-stage heating pipe is connected to the hot water input end of the mixing valve 185.

[0040] The dual evaporation system includes a first evaporator 155 and a second evaporator 156. The first evaporator 155 is located in a cold water tank 154 and has a push-type ice discharge mechanism installed on its top. The second evaporator 156 is installed at the bottom of the cold water tank 154 and has a temperature sensor 157 installed in the cold water tank 154. The first evaporator 155 and the second evaporator 156 are connected by a condensation circulation pipeline.

[0041] In the above embodiments, it should be noted that the top of the back door 113 is provided with a buckle and a slot. Pulling the slot outwards to flip the back door 113 allows for the installation or replacement of the PCT filter element 132 and the RO filter element 133. The PCT filter element 132 is a water treatment filter element, which is usually used in the first filtration step of water treatment equipment to ensure that the water entering the RO filter element 133 is relatively clean, which helps to improve the service life and water treatment efficiency of the RO filter element 133. The RO filter element 133 is a reverse osmosis filter element, which is mainly used in reverse osmosis water treatment systems. Its core function is to perform deep filtration of water through a semi-permeable membrane.

[0042] The pure water tank 116 and the raw water tank 115 are an integrated double-cavity water tank combination. The raw water tank 115 is equipped with a water inlet. A self-priming pump is installed at the output end of the raw water tank 115 to output raw water into the equipment. The side covers of the pure water tank 116 and the raw water tank 115 can be opened for easy cleaning. A sealing ring is provided on the inner edge of the cover. The ultraviolet rays released by the ultraviolet disinfection base 114 pass through the bottom of the pure water tank 116 and irradiate the raw water tank 115 to achieve the effect of disinfecting the water in the pure water tank 116 and the raw water tank 115 at the same time.

[0043] After filling the raw water tank 115 with water, install the raw water tank 115 and the pure water tank 116 on the top surface of the ultraviolet disinfection base 114. Then, start the self-priming pump in the raw water tank 115 to sequentially input the water in the raw water tank 115 into the PCT filter element 132 and the RO filter element 133. The water filtered by the PCT filter element 132 and the RO filter element 133 flows back to the pure water tank 116. Then, start the cold water input pipeline to inject the water in the pure water tank 116 into the cold water tank 154. Start the compressor 142 and the condenser 143. The condensation circulation pipeline introduces the coolant output from the condenser 143 into the second evaporator 156 to cool the water in the cold water tank 154.

[0044] When cold water is needed: water in the cold water tank 154 is introduced into the mixing valve 185 through the cold water input pipe and then output. When hot water is needed: water in the pure water tank 116 is heated by activating the two-stage heating pipe and then introduced into the mixing valve 185 and then output. The mixing valve 185 controls the mixing ratio of cold and hot water to achieve the effect of outputting cold and hot water.

[0045] The insulation panel 141 has a polystyrene interlayer, which has good thermal insulation performance. The insulation panel 141 divides the inner shell 111 into two areas: a hot zone and a cold zone. By concentrating the heat-generating equipment (such as the compressor 142, condenser 143, etc.) in the hot zone and placing the cooling ice-making structure (such as the cold water tank 154, ice storage tank 151, etc.) in the cold zone, the heat conduction loss can be effectively reduced, thereby reducing energy consumption and improving the overall energy efficiency of the equipment. Furthermore, separating the heat source and the cold source can prevent the hot airflow from directly affecting the temperature of the cold zone, ensuring that the cold zone is kept at a lower temperature, thereby improving the ice-making efficiency and speed.

[0046] In standby mode, the water in the cold water tank 154 is cooled by the second evaporator 156 in the dual evaporation system, and the water temperature is precisely maintained at slightly above the freezing point (e.g., 0.1°C to 0°C). When ice is needed, the condensing circulation pipeline switches to the first evaporator 155 to force heat exchange with the water in the cold water tank 154 that is at the freezing point, causing it to crystallize rapidly into ice. Then, the push-type ice discharge mechanism is activated to move the first evaporator 155 above the ice storage tank 151, allowing the ice to fall into the ice storage tank 151, and then the ice discharge is completed. This effectively reduces the energy consumption of the compressor and makes effective use of the cooling capacity generated by the condenser 143, avoiding ineffective ice melting and re-ice making cycles inside the system. The temperature sensor 157 installed in the cold water tank 154 is used to detect the water temperature in the cold water tank 154 in real time, assisting the second evaporator 156 in precisely maintaining the water temperature at slightly above the freezing point.

[0047] like Figure 1 , Figure 4 and Figure 5 As shown, a tabletop ultraviolet sterilization, water purification, heating, cooling and ice-making integrated device also includes a central control system including a central control compartment 121, which is installed on the top of the outer casing 111. A circuit board 123 and a power transformer 124 are installed inside the central control compartment 121. The circuit board 123 and the power transformer 124 are electrically connected. An operation panel 122 is connected to the circuit board 123 and is installed on the upper part of the front panel 112.

[0048] In the above embodiments, it should be noted that the electronic components mounted on the circuit board 123 include:

[0049] Microcontroller (PCL): Used to control the operation of equipment, including the start and stop of motors, water pumps, heaters, coolers, ultraviolet lamps, etc.

[0050] Rectifier: Used to convert alternating current (AC) to direct current (DC), typically constructed using diodes;

[0051] Filter capacitor: Used to smooth the rectified DC power, making the output voltage more stable;

[0052] Relays or solid-state relays: used to control the switching of high-power devices (such as heaters and compressors). Microcontrollers manage the operation of these devices through relays.

[0053] In addition, the circuit board 123 is electrically connected to a variety of sensors, including a temperature sensor, a flow sensor and a water level sensor, for real-time monitoring of the equipment status and water quality;

[0054] The power transformer 124 is used to convert AC voltage into the required DC voltage to provide a stable power supply for the circuit; the operation panel 122 is used as a user interface to facilitate user operation and settings.

[0055] Control commands are input from the control panel 122 to the microcontroller (PCL) in the circuit board 123, and then the microcontroller (PCL) and relays in the circuit board 123 control the start and stop of each component in the device.

[0056] like Figure 2 , Figure 6 , Figure 8 - Figure 13 As shown, a tabletop ultraviolet sterilization, water purification, heating, cooling, and ice-making integrated device further includes a condensing circulation pipeline including an electrically controlled diverter valve 172. A condenser output pipe 171 is connected between the input end of the electrically controlled diverter valve 172 and the output end of the condenser 143. The outer wall of the condenser output pipe 171 is wrapped with heat insulation material. One output end of the electrically controlled diverter valve 172 is connected to the first evaporator input pipe 173, and the other output end is connected to the second evaporator input pipe 174. The first evaporator input pipe 173 is connected to the input end of the first evaporator 155. Several ice-making sticks are installed at the bottom of the first evaporator 155. The output end of the first evaporator 155 is connected to the first evaporator output pipe 175. The second evaporator input pipe 174 is connected to the input end of the second evaporator 156. The output end of the second evaporator 156 is connected to the second evaporator output pipe 176. Both the first evaporator output pipe 175 and the second evaporator output pipe 176 are connected to the input end of the compressor 142.

[0057] In the above embodiments, it should be noted that the electronically controlled diverter valve 172 is a valve used to control the flow direction of fluid (liquid or gas) and to switch the output path of the condenser 143. When the equipment is in standby mode, the electronically controlled diverter valve 172 is controlled by the microcontroller (PCL) to connect the condenser output pipe 171 and the second evaporator input pipe 174 to introduce the refrigerant into the second evaporator 156. After the second evaporator 156 completes heat exchange, the refrigerant is introduced into the compressor 142 through the second evaporator output pipe 176 for the next round of compression.

[0058] When the equipment makes ice, the microcontroller (PCL) controls the electronically controlled diversion valve 172 to connect the condenser output pipe 171 and the first evaporator input pipe 173 to introduce the refrigerant into the first evaporator 155. After the first evaporator 155 completes heat exchange, ice will condense on the surface of the ice-making rod at its bottom. Then, the refrigerant is introduced into the compressor 142 through the first evaporator output pipe 175 for the next round of compression.

[0059] like Figure 2 , Figure 5 , Figure 6 and Figure 10 - Figure 13As shown, a tabletop ultraviolet sterilization, water purification, heating, cooling, and ice-making integrated device further includes a propulsion-type ice-dispensing mechanism comprising a sliding bracket 161. The sliding bracket 161 is installed on both sides of the bottom of the central control compartment 121. A slide rail 162 is installed at the center of the bottom of the central control compartment 121. A slider 163 is slidably installed on the slide rail 162. A U-shaped clamp 164 is installed at the bottom of the slider 163. A connecting rod 169 is installed on one side of the U-shaped clamp 164. The connecting rod 169 is connected to the output end of a hydraulic rod 168. The hydraulic rod 168 is installed at the bottom of the central control compartment 121. The propulsion-type ice-dispensing mechanism includes a crossbeam 165. The middle part of beam 165 passes between U-shaped clip 164 and slider 163. A groove is provided on the inner side of U-shaped clip 164. A protrusion is provided in the middle of beam 165. The protrusion in the middle of beam 165 is slidably installed in the groove on the inner side of U-shaped clip 164. Both ends of beam 165 are slidably installed in sliding bracket 161. Evaporator connector No. 1 166 is installed at one end of beam 165 and evaporator connector No. 2 167 is installed at the other end. Evaporator connector No. 1 166 connects the input end and output end of the first evaporator 155. Evaporator connector No. 2 167 connects the middle part of the first evaporator 155.

[0060] In the above embodiment, it should be noted that the first evaporator 155 is also connected to a defrosting solenoid valve. The defrosting solenoid valve is linked with the temperature sensor 157 through the microcontroller. When the microcontroller detects that the temperature of the first evaporator 155 is too low or there is an ice-forming signal, the microcontroller will activate the defrosting solenoid valve, open the valve, allow the heat medium to flow, and carry out the defrosting operation. Once the frost melts or the temperature reaches the set value, the solenoid valve will close and the refrigeration cycle will be restored.

[0061] After ice blocks condense on the ice-making rod of the first evaporator 155, the hydraulic rod 168 is activated to push the connecting rod 169, which in turn moves the U-shaped clamp 164 laterally. At the same time, the U-shaped clamp 164 moves the crossbeam 165 laterally, and the two ends of the crossbeam 165 slide vertically up and down along the U-shaped clamp 164 under the action of the sliding bracket 161. This causes the crossbeam 165 to slide the first evaporator 155 in a curved path, so as to lift the ice blocks on the ice-making rod of the first evaporator 155 and move them above the ice storage tank 151. Then, the ice-melting solenoid valve is activated to heat the ice-making rod of the first evaporator 155, completing the removal of the ice blocks. The removed ice blocks fall into the ice storage tank 151.

[0062] like Figure 2 - Figure 9As shown, a tabletop ultraviolet sterilization, water purification, heating, refrigeration, and ice-making integrated device further includes a cold water input pipeline comprising a cold water inlet pump 191, the input end of which is connected to a cold water inlet pipe 192, which is connected to a pure water tank 116; the output end of the cold water inlet pump 191 is connected to a cold water inlet pipe 193, which is connected to a cold water tank 154; a cold water outlet pump 195 is installed in the middle of the cold water outlet pipe 194; and a two-stage heating pipeline comprising a heating inlet pump 181, the input end of which is connected to a heating inlet pipe 182, which is connected to a pure water tank 116; the output end of the heating inlet pump 181 is connected to the input end of a preheating pipe 183, which is located on the heat dissipation surface of a condenser 143. The output terminal 83 is connected to the input terminal of the electric heater 184. The output terminal of the electric heater 184 is connected to the hot water input terminal of the mixing valve 185. A filter element bracket 131 is installed inside the rear flip door 113. Both the PCT filter element 132 and the RO filter element 133 are inserted and installed in the filter element bracket 131. The back of the heat insulation plate 141 is equipped with a first filter element interface 134 and a second filter element interface 135. The first filter element interface 134 can be connected to the PCT filter element 132 socket. The input terminal of the first filter element interface 134 is connected to the raw water tank 115. The output terminal of the first filter element interface 134 is connected to the input terminal of the second filter element interface 135. The second filter element interface 135 can be connected to the RO filter element 133 socket. The output terminal of the second filter element interface 135 is connected to the pure water tank 116.

[0063] In the above embodiments, it should be noted that by starting the cold water inlet pump 191, water in the pure water tank 116 can be injected into the cold water tank 154 through the cold water inlet pipe 192 and the cold water input pipe 193. By starting the cold water outlet pump 195, water in the cold water tank 154 can be injected into the mixing valve 185. By starting the heating inlet pump 181, water in the pure water tank 116 can be introduced into the preheating pipe 183 through the heating inlet pipe 182. The preheating pipe 183 can recover the waste heat generated by the heat dissipation surface of the condenser 143. Then, the water in the preheating pipe 183 is introduced into the electric heater 184. The electric heater 184 is started to heat the water. The heated water is injected into the mixing valve 185. By starting the mixing valve 185, hot water and cold water can be mixed in a certain proportion and output from the outlet 186 to achieve more precise water temperature control.

[0064] Water in the raw water tank 115 is filtered through the first filter cartridge interface 134 into the PCT filter cartridge 132 and then output. After being filtered through the second filter cartridge interface 135 into the RO filter cartridge 133, it is output to the pure water tank 116 to achieve the filtration of the raw water. The water in the pure water tank 116 meets the drinking standards and can be consumed directly.

[0065] like Figure 1 - Figure 4 , Figure 10 , Figure 11 and Figure 14 As shown, a tabletop ultraviolet sterilization, water purification, heating, cooling, and ice-making integrated device includes an ultraviolet lamp assembly on the top surface of an ultraviolet disinfection base 114, a water jug ​​117 installed on the front side of the ultraviolet disinfection base 114, a water receiving tray 118 installed at the lower end of the front panel 112, an ice outlet 119 in the middle of the front panel 112, a water outlet 186 in the middle of the front panel 112, a cooling fan 144 installed on the heat dissipation surface of the condenser 143, a motor 153 installed at the rear end of the ice storage tank 151, the output end of the motor 153 passing through the ice storage tank 151 and a fixed ice-removing screw 152 installed therein, the front end of the ice storage tank 151 connected to the ice outlet 119, and a return water pipe connected to the bottom of the ice storage tank 151, which is connected to a cold water tank 154.

[0066] In the above embodiment, it should be noted that after the ice block falls into the ice storage tank 151, the microcontroller starts the motor 153 to drive the ice-retrieving screw 152 to rotate, so as to push the ice block to the ice outlet 119 and complete the ice discharge.

[0067] By activating the ultraviolet lamp group on the top surface of the ultraviolet disinfection base 114 to continuously irradiate the pure water tank 116 and the raw water tank 115, the bacteria in the water tank can be killed.

[0068] By activating the cooling fan 144, the air inside and outside the switch housing 111 is circulated, and the condenser 143 is cooled down, which can effectively prevent the condenser 143 from overheating.

[0069] The usage process of this invention is as follows: After filling the raw water tank 115 with water, those skilled in the art install the raw water tank 115 and the pure water tank 116 on the top surface of the ultraviolet disinfection base 114. Then, the self-priming pump in the raw water tank 115 is started. The water in the raw water tank 115 is introduced into the PCT filter element 132 through the first filter element interface 134 and then output after filtration. After passing through the second filter element interface 135, it is introduced into the RO filter element 133 and then output to the pure water tank 116. Starting the cold water inlet pump 191 can further purify the water. Water in water tank 116 is injected into cold water tank 154 through cold water inlet pipe 192 and cold water inlet pipe 193. Compressor 142 and condenser 143 are started. When the equipment is in standby mode, refrigerant is introduced into second evaporator 156 through electronically controlled diversion valve 172, connecting condenser outlet pipe 171 and second evaporator inlet pipe 174. Second evaporator 156 cools the water in cold water tank 154 and precisely maintains the water temperature slightly above freezing. When ice is needed, electronically controlled diversion valve 172 is activated to connect... The condenser output pipe 171 and the first evaporator input pipe 173 introduce refrigerant into the first evaporator 155. The first evaporator 155 performs forced heat exchange on the water in the cold water tank 154 that is at its freezing point, causing it to rapidly crystallize into ice. Then, the hydraulic rod 168 is activated to push the connecting rod 169, which in turn moves the U-shaped clamp 164 laterally. At the same time, the U-shaped clamp 164 moves the crossbeam 165 laterally, and the two ends of the crossbeam 165 move vertically up and down along the U-shaped clamp 164 under the action of the sliding bracket 161. The crossbeam 165 slides, causing the first evaporator 155 to slide in a curved path, lifting the ice block from the ice-making rod of the first evaporator 155 and moving it above the ice storage tank 151. Then, the ice-melting solenoid valve is activated to heat the ice-making rod of the first evaporator 155, completing the removal of the ice block. The removed ice block falls into the ice storage tank 151. After the ice block falls into the ice storage tank 151, the starting motor 153 drives the ice-removing screw 152 to rotate, so as to push the ice block to the ice outlet 119 and complete the ice removal effect.

[0070] When hot and cold water are needed, the cold water outlet pump 195 is started to inject water from the cold water tank 154 into the mixing valve 185. The heating inlet pump 181 is started to introduce water from the pure water tank 116 into the preheating pipe 183 through the heating inlet pipe 182. The preheating pipe 183 can recover the waste heat generated by the heat dissipation surface of the condenser 143. Then the water in the preheating pipe 183 is introduced into the electric heater 184. The electric heater 184 is started to heat the water. The heated water is injected into the mixing valve 185. By controlling the mixing valve 185, hot and cold water are mixed in a certain proportion and output from the outlet 186.

[0071] The above description is merely a preferred embodiment of the present invention. Any person skilled in the art can modify the present invention or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of the present invention fall within the scope of protection claimed by the present invention.
